2013-01-17usb: musb: fix dependency on transceiver driverMing Lei
This patch let glue driver return -EPROBE_DEFER if the transceiver is not readly, so we can support defer probe on musb to fix the below error on 3.7-rc5 if transceiver drivers are built as module: [ 19.052490] unable to find transceiver of type USB2 PHY [ 19.072052] HS USB OTG: no transceiver configured [ 19.076995] musb-hdrc musb-hdrc.0.auto: musb_init_controller failed with status -19 [ 19.089355] musb-hdrc: probe of musb-hdrc.0.auto rejects match -19 [ 19.096771] driver: 'musb-omap2430': driver_bound: bound to device 'musb-omap2430' [ 19.105194] bus: 'platform': really_probe: bound device musb-omap2430 to driver musb-omap2430 [ 19.174407] bus: 'platform': add driver twl4030_usb [ 19.179656] bus: 'platform': driver_probe_device: matched device twl4030_usb with driver twl4030_usb [ 19.202270] bus: 'platform': really_probe: probing driver twl4030_usb with device twl4030_usb [ 19.214172] twl4030_usb twl4030_usb: HW_CONDITIONS 0xc0/192; link 3 [ 19.239624] musb-omap2430 musb-omap2430: musb core is not yet ready [ 19.246765] twl4030_usb twl4030_usb: Initialized TWL4030 USB module [ 19.254516] driver: 'twl4030_usb': driver_bound: bound to device 'twl4030_usb' [ 19.263580] bus: 'platform': really_probe: bound device twl4030_usb to driver twl4030_usb Cc: Sebastian Andrzej Siewior <sebastian@breakpoint.cc> Cc: <stable@vger.kernel.org> v3.8 Signed-off-by: Ming Lei <ming.lei@canonical.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

2013-01-17usb: musb: Double buffering issues in host mode TXsupriya karanth
Whenever an URB is programmed for transfer, the TXFIFO is flushed. This results in valid packets of the previous transfer to get flushed when double buffering is enabled (The MUSB_TXCSR_FIFONOTEMPTY bit in TXCSR is set indicating that a packet in the FIFO is yet to be sent) For ex:- In Host mode Audio, noise is heard in the headset when double buffering is enabled on the ISO endpoint. The fifo flush is removed for double buffering case. The fifo is now flushed only in cases of error or when aborting a transfer. Also, In Host MSC case, data toggle errors are seen when double buffering is enabled on the bulk endpoint. Whenever an URB is programmed for transfer, the data toggle is set manually resulting in data toggle errors on the bus. Leave the data toggle handling upto the hardware in the double buffering case.

2013-01-15TTY: switch tty_flip_buffer_pushJiri Slaby
Now, we start converting tty buffer functions to actually use tty_port. This will allow us to get rid of the need of tty in many call sites. Only tty_port will needed and hence no more tty_port_tty_get in those paths. Now, the one where most of tty_port_tty_get gets removed: tty_flip_buffer_push. IOW we also closed all the races in drivers not using tty_port_tty_get at all yet. Also we move tty_flip_buffer_push declaration from include/linux/tty.h to include/linux/tty_flip.h to all others while we are changing it anyway.

While here, two other changes suggested by Alan: - the comment referering to 7.2.1.1 has been updated to 7.2.1 which is the correct source of the action. - the check for hubs with zero ports has been removed. - compute bus power by full_load * num_ports on root hubs Acked-by: Alan Stern <stern@rowland.harvard.edu> Acked-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2013-01-10usb: musb: set TXMAXP and AUTOSET for full speed bulk in device modesupriya karanth
The TXMAXP register is not set correctly for full speed bulk case when the can_bulk_split() is used. Without this PIO transfers will not take place correctly The "mult" factor needs to be updated correctly for the can_bulk_split() case The AUTOSET bit in the TXCSR is not being set if the "mult" factor is greater than 0 for the High Bandwidth ISO case. But the "mult" factor is also greater than 0 in case of Full speed bulk transfers with the packet splitting in TXMAXP register Without the AUTOSET the DMA transfers will not progress in mode1 [ balbi@ti.com : add braces to both branches ] Signed-off-by: supriya karanth <supriya.karanth@stericsson.com> Signed-off-by: Praveena NADAHALLY <praveen.nadahally@stericsson.com> Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Felipe Balbi <balbi@ti.com>
